Circuit breakers are important safety components used in electrical systems to protect electrical components from damage. They open or close an electrical circuit when conditions in the circuit exceed the operating limits. IELHK111-28680-1-V circuit breakers are widely used in power systems, home appliances, automotive and industrial equipment applications.

IELHK111-28680-1-V circuit breakers feature an excellent pressure-sensitive design that helps provide circuit protection from short circuits, ground faults, overloads, and voltage transients in sensitive appliances and electrical equipment. This type of circuit breakers is typically used in automotive applications such as alternators, starters, charging circuits, motorized equipment, and lighting systems.

The IELHK111-28680-1-V circuit breakers are designed with a hard-to-trip operation and provide good current carrying capability with minimal voltage drop, superior overload protection, and fast response times to protect critical equipment in automotive, industrial, and power system applications. The circuit breakers have a three-phase voltage rating of up to 286V, a thermal current limiting response, and are UL 489 listed. They are also designed to meet international safety standards, including the Standard for GFCIs and RCDs, IEC 60947-2-2, EN 60950-1, and UL 2579.

The working principle of IELHK111-28680-1-V circuit breaker is a combination of a hydraulic-magnetic switch and an electromagnetic mechanism. The hydraulic-magnetic switch consists of a spring-loaded plunger which is held in the “on” position by a magnetic field. When an electrical current greater than the rated value passes through the switch, the plunger is forced open by the high current. This interrupts the electrical circuit and trips the breaker. The electromagnetic mechanism is composed of a solenoid and a contact assembly. When the plunger is forced open, the solenoid is actuated to move the contact assembly and break the connection between the two terminals. This terminates the current flow and protects the electrical equipment.

IELHK111-28680-1-V circuit breakers can be used in various applications including household appliances, industrial machinery, electric motors, and power supplies. The IELHK111-28680-1-V circuit breakers are designed to be reliable, durable, and simple to install, making them ideal for protecting sensitive electrical equipment from destruction due to short circuit or overload conditions. In addition, these circuit breakers provide excellent current carrying capabilities with minimal voltage drop and excellent overload protection.
